Abstract:The 19th National Congress of the CPC put forward that the construction of ecological civilization is a thousand-year plan that concerns the sustainable development of the Chinese nation. On the basis of the theory of "two mountains" , the systematic governance of the life community of "mountains, rivers, forests, fields, lakes and grasses" was carried out. Mine geological environment is a key link of ecological environment, the destruction of mine geological environment directly leads to the unbalance of mine ecological environment. The geological environmental problems in mines are regionality, complexity and diversity. Therefore, it is necessary to carry out targeted exploration in the restoration and treatment of the geological environment in mines, and to put forward various treatment schemes for comparison and selection, selection of the most practical mine treatment methods. As a comprehensive analysis and evaluation method of engineering economy, value engineering has achieved good evaluation results in various fields. Based on the principle of value engineering, this paper analyzed the analysis flow and optimization model of value engineering, taking cutting slope as the optimal scheme, it had strong adaptability in the north, carefully combed the characteristics of mine geological environment restoration, and made full use of the principle of value engineering to optimize the analysis of the scheme in the comparison of the treatment scheme, to make the governance Scheme more targeted and integrated, combined to achieve higher economic benefits.
